Description
Technical field
The utility model relates to a kind of PIG in Oil Pipeline, the flexible explosion jet-pipe cleaner of especially a kind of crude oil pipeline.
Background technology
Pipeline transportation is the most quick, economic, reliable major way in oil gas transportation, and the pipeline transportation of oil gas has played important function from production, refining, storage and the overall process to user of crude oil, natural gas.The operation of long-time, the long distance of oil pipeline, will cause the inner fouling occurring in various degree, and the generation of dirt causes serious impact to oil transportation operation, and waste mass energy, therefore needs regularly pipeline to be carried out to scale removal, and this just need to use cleaning apparatus for pipes.
In Chinese utility model patent description CN200620099889.4, disclose a kind of jet flow tube cleaner, the outward appearance of this wiper is bullet shape, and inside is hollow, and afterbody is uncovered, and front end has jet orifice, and outer wall has jet groove, has certain snaking ability.Although this wiper is simple in structure, on outer wall, do not increase the leather cup device of resistance, when it moves in pipeline, wiper cavity internal pressure is less, and after jet orifice, jet pressure is low, and impulsive force is little, scaling effect is poor, can not disposable thorough removing sludge on inner wall of pipeline.Because this wiper is long bar shape, while operation at channel bend place, easily there is blocking simultaneously.
In Chinese utility model patent description CN101653773A, disclose a kind of crude oil pipeline sand, wax high pressure jet flow wiper, changed wiper back seat and urceolus screwed connection, injector head is fixed on urceolus, and leather cup is fixed on urceolus; Support is fixed on urceolus inside, support is provided with hole slot towards the direction of back seat inner core is installed, in inner core, be provided with spring, spring is supported by the spring support in inner core, the other end of spring is provided with valve ball, and valve ball, by inner core, spring, the common restriceted envelope of back seat position, has groove on the barrel of inner core end, on support, have a hole and spring Limit screw cooperating, spring Limit screw heads on spring support.This wiper is simple in structure, easy to maintenance, can reach the object of pigging.
But this wiper nozzle spray regime is radially narrower, because dirt is all created on inner-walls of duct, be difficult to rely on that the impulsive force of High-Pressure Water is disposable that dirt is cleaned out with this jet flow tube cleaner, cleaning effect is not ideal enough.Meanwhile, while operation at channel bend place, handling capacity is poor, still has blocking phenomenon.
Utility model content
For above-mentioned prior art, problem to be solved in the utility model be to provide a kind of disposable thorough removing sludge on inner wall of pipeline, scaling effect good, can pass through smoothly the crude oil pipeline wiper of channel bend.
For addressing the above problem, the technical solution adopted in the utility model is as follows: the flexible explosion jet-pipe cleaner of crude oil pipeline, comprise propelling cavity, jet nozzle, universal connector, hose connection device, exciting device, release of pressure cavity, on described propelling cavity, clamp nut is installed, leather cup is chipped with scraping, described propelling cavity rear end is hollow cylindrical, front end is the conulite shape that cross section reduces gradually, described release of pressure cavity is the large shuttle body shape in the two little intermediate cross-sections of end section, universal connector is passed through in described propelling cavity and described release of pressure cavity corresponding connection parts position, the dual connection of hose connection device, on described release of pressure cavity, jet nozzle is installed, described exciting device one end is arranged on release of pressure cavity, the other end is arranged on jet nozzle.
Adopt such wiper, just can select scrape corresponding with its size to chip and leather cup according to the size of internal diameter of the pipeline, be assembled into the wiper that is adapted to internal diameter of the pipeline.Wiper advances under waterpower promotes, and through advancing cavity front end conulite, due to reducing suddenly of conulite cross section, water flow pressure sharply increases; Current enter release of pressure cavity through flexible pipe, and due to the shuttle body structure of release of pressure cavity, current overflow section increases suddenly, and water flow pressure sharply reduces again, and when pressure is during lower than gas disjoining pressure, the bubble dissolving in current will be separated.The a part of fluid impact exciting device flowing out from flexible pipe, make the compression of the oscillator other end be with alveolate current, make its supercharging, there is under pressure explosion in bubble, explosion moment produces large energy, bubble current are around ejected through jet nozzle, strong impulse piping internal dirt, scaling effect is good.Simultaneously, when bubble explosion, exciting device is produced to a reaction force, it is moved towards hose end, exciting device constantly moves back and forth under hose end fluid impact and the effect of bubble blasting impact like this, constantly compressed air bubble produces explosion, strong impulse piping inwall, disposablely thoroughly takes out stains, and scaling effect is good.Meanwhile, it is certain flexible that universal connector and hose connection device have this wiper, can pass through smoothly channel bend, is difficult for occurring blocking phenomenon.
As further improvement of the utility model, described release of pressure cavity is along the circumferential direction gone up and is evenly had release of pressure passage, and release pressure forms environment under low pressure, is the necessary condition that bubble forms; The dirt that the liquid flowing out in release of pressure passage cleans out injection stream plays souring, promotes dirt and flows forward along pipeline.
Further improve as of the present utility model, described exciting device comprises oscillator and is arranged on the spring at oscillator two ends.
Further improve as of the present utility model, described jet nozzle is along the circumferential direction gone up and is evenly provided with fluidic channel again.
For the utlity model has the flexible explosion jet-pipe cleaner of crude oil pipeline that advances cavity, preferably advance cavity to be provided with flange, scrape and chip and leather cup for location and installation.
Improve as another step of the present utility model, described hose connection device comprises hose coupling, flexible pipe, and described hose coupling is threaded with described propelling cavity, release of pressure cavity, forms fluid course, prevents water flow pressure loss.Described universal connector comprises the first petal body and the second petal body, and described the first petal body, the second petal body are arranged on and are advanced on cavity, release of pressure cavity by thread connection respectively, and protection flexible pipe is not pulled off.Described the first petal body is along the circumferential direction gone up and is evenly provided with depressed part, described the second petal body is along the circumferential direction gone up and is evenly provided with protuberance, described depressed part matches with corresponding protuberance, forms flexible connection, makes this wiper run to channel bend place and has stronger handling capacity.
The beneficial effects of the utility model are: the utility model can disposable thorough removing sludge on inner wall of pipeline, and scaling effect is good, has stronger channel bend handling capacity simultaneously, are difficult on occurring blocking phenomenon at snaking.
